Authoritative SEO Optimization Explained: Why Does Google Still Need Ads? Complete Guide to Multilingual Website Strategies

随着全球化的推进，多语言网站已成为企业拓展国际市场的重要战略工具。在构建多语言网站时，企业面临着一个关键决策：使用独立域名还是子目录来展示不同语言的内容。

With the advancement of globalization, multilingual websites have become a strategic tool for businesses to expand into international markets. When building multilingual websites, companies face a critical decision: whether to use separate domains or subdirectories to present content in different languages.

一、子域名与子目录的核心差异 | Core Differences Between Subdomains and Subdirectories

• 子目录：父目录中的目录结构（如：example.com/en/）
• Subdirectory: Directory structure within a parent directory (e.g., example.com/en/)

2. SEO影响 | SEO Impact

• 子域名：每个子域名可被视为独立网站进行排名，但可能分散主域权重
• Subdomain: Each can be ranked as an independent site, but may dilute main domain authority
